I have a habit of waking up and grabbing a coffee or filling up a bowl with cereal before I do anything else. This is certainly something I grappled with. Every morning, before and after eating and before or after exercise are useful points to grab and blow. The more you do it, the more insightful the data will be. The first thing to accept with Lumen is that you're going to need to be committed to using it on a regular basis. You can take these readings at any time of the day, but Lumen recommends taking them first thing in the morning to help build a nutrition plan, which gives you a recommended breakdown of carb, fat and protein intake to help get you to that more flexible metabolic state. More recently, it's introduced an Apple Watch app to grab data like tracked workouts, sleep to offer more personalised nutrition recommendations to work on building a more flexible metabolism. In that time it's added compatibility with Garmin's Connect platform including introducing a dedicated Lumen Connect IQ app. It's also useful when you want to know if you've got the right fuel in the tank to tackle a tough workout.Īfter raising big crowdfunding bucks (almost $2 million), the $199 device finally launched back in 2020 and requires a $19 monthly subscription. It says it can help you lose weight in a more natural way, make your body less dependent on snacking and boost energy levels and general health. InsideTracker pairs with Garmin for body age insights.With that information gathered by analysing the carbon dioxide in your breath, Lumen says it can help to train the body to switch between using those fat and carbohydrate fuel sources. You inhale and exhale into it, and it can tell whether your body is burning carbohydrates or fat. It has the appearance of a vape, and promises to track your metabolism.

Lumen isn't a wearable, but it does play nicely with them. Ever since I first started testing wearables, I've been hoping that something would come along that could help me take better stock over what kind of food I was putting in my body and understand the impact it had on my body.
